| DESCRIPTION: EPOCAST® 1622 FST A/B is a two-component, low density, pumpable FST epoxy syntactic material designed for potting fasteners and panel joining of honeycomb structures used in aerospace interior applications. It is easily extruded through Semco ® dispensing nozzles, yet does not flow after it has been applied. EPOCAST® 1622 FST A/B sets quickly at room temperature and is well suited for aerospace applications requiring a rapid component assembly.&& |
